Bearing disassembly is scheduled maintenance, bearing replacement. After disassembly, if the bearing is still in use, or if it is necessary to check the condition of the bearing, the disassembly shall be carried out with the same care as during installation. Pay attention not to damage the parts of the bearing, especially interference with the disassembly of the bearing, the operation is difficult.
It is also important to design and manufacture disassembly tools as needed. In the process of disassembly, according to the drawings to study the disassembly method, order, investigation of the bearing conditions, in order to obtain the disassembly operation is foolproof.
The outer ring of the outer ring shall be equipped with screws for extruding screw in several places on the circumference of the shell in advance. Screw the screw equally on one side and remove it at the same time. These screw holes are usually covered with the blind plug, tapered roller bearings, and other detachable bearings. Several incisions are made in the housing block shoulder.
The removal of the inner ring can be done with a press machine. At this point, pay attention to let the inner ring bear its pulling force. In addition, the pull-out fixture shown is also mostly used, no matter which fixture, it must be firmly stuck in the inner ringside. To this end, we need to consider the size of the shaft block shoulder, or research in the block shoulder processing groove, in order to use a pulling clamp.
The inner ring of the large bearing is disassembled by the oil pressure method. Oil pressure is applied to the oil hole of the bearing for easy drawing. The large width of the bearing oil pressure method and drawing fixture, for disassembly.
The inner ring of cylindrical roller bearings can be removed by induction heating.The method of heating the part in a short time and drawing the inner ring after expansion.Induction heating is also used where large Numbers of these bearing inner rings are required.
